To altro/710m tr/tay concern:

Be it known that I, ARTHUR TULLY McCracnnN, a citizen of the Unit-ed Stat-es, residing at Sulphur Springs, in the count-y of Benton and State of Arkansas, have 1nvented a new and useful Hydrocarbon- Burner, of which the following is a specication.

The invention relates to improvementsin hydrocarbon burners. v

The object of the present invention 1s to improve the construction of hydrocarbon burners and to provide a simple, inexpensive, and eiiicient burner designed for use in cooking and heating stoves, and adapted to be supported directly upon the grate of a stove, with its supply pipe extending between the grate bars, and capable of consuming coal oil and similar fuels with a blue flame.

1With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a central vertical sectional view of a hydrocarbon burner constructed in accordance with this invention, and shown applied to a stove, a portion thereof being illustrated in dotted lines. Fig. 2 is a plan view of the same. Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, the hydrocarbon burner comprises in its construction a cylindrical casing 1 designed to be arranged within the fire box of a Stove 2 and provided with a horizontal bottom 3 having an air inlet opening A. The cylindrical burner casing, which is provided with a removable cover or top 5, is supported in a superimposed position with relation to the grate 6 of the stove 2 by a depending cylindrical neck 7 surrounding the bottom opening i and secured to the lower face of the bottom in spaced relation with the said opening 4: by means of lugs or edge thereof, are fastened to the bottom by` rivets or other suitable means, but the neck may be applied to the bottom of the burner casing in any other desired manner. The top or cover 5 is provided with a depending flange 9 and it has burner openings 10 at which mixed hydrocarbon vapor and air are adapted to burn with a perfectlyblue flame. The ange 9 of the top or cover 5 fits within the burner casing, which contains a gas or vapor generating coil 11 located a short distance below the top 5 of the casing and connected at one end with a supply pipe 12 and at the other end with a branch pipe 13 depending from the inner end of the coil and extending downwardly therefrom through the bottom of the casing and into the neck 7. The depending branch pipe is provided at its lower end with an arm 11i extending inwardly and upwardly and having a terminal discharge nozzle 15 preferably projecting slightly into the burner casing at the bottom opening thereof for discharging vaporized coal oil or other hydrocarbon into the burner casing for causing such vaporized fuel to mix with air prior to burning at the top of the casing. The supply pipe 12 extends downwardly between the grate bars and may be connected with any suitable source of fuel supply.

The fuel supply pipe, the depending branch, and the generating coil are preferably constructed of a single piece of metallic tubing, as shown, but one or more pieces may be employed in the construction of the generating coil, the supply pipe, and the depending branch pipe.

When the fuel is turned on there will be suliicient vapor to start the burner, and after the burner is lighted, the heat will vaporize the fuel within the generating coil and cause such vaporized fuel to be injected into the burner casing from the discharge nozzle 15.

lf desired, the device may be equipped with a suitable starting cup to enable the burner-to be heated before lighting the same at the top of the burner casing.

`What is claimed is:

A burner of the class described including a casing constituting a mixing chamber and comprising side walls, a top having burner openings, and a bottom provided with a central opening, a neck connected with the bottom of the easing and surrounding the opening thereof and adapted to rest directly upon the grate of a stove and support the easing in a superimposed position with relation to the said grate, a vapor generating coil located within the easing below the top thereof, a supply pipe connected with one end of the generating coil and adapted to extend between the grate bars, and a depending branch pipe connected with the other end of the heating coil and extendingdownwardly therefrom into the said neck and provided with an arm having a terminal nozle arranged to discharge vaporized fuel into the burner easing.

In testimony that I Claim the foregoing as my own I have hereto aiiixed my Signature in the presence oi' two witnesses.

ARTHUR TULLY MCGRACKEN.
